Answer:
28
Step-by-step explanation:
You want the smaller of the two factors of 896 that have the ratio 8:7.
<h3>Setup</h3>
Let x represent the smaller of the two factors (the one we want to find). Then the larger factor is (8/7)x, and their product is ...
x(8/7)x = 896
(8/7)x² = 896
<h3>Solution</h3>
Multiplying by the inverse of the coefficient of x², we have ...
x² = (7/8)(896) = 784
x = √784 = 28 . . . . . . . . take square root
The smaller of the two numbers is 28.

<em>Additional comment</em>
The larger is (8/7)(28) = 32.
I’m literally stuck on the same kind of stuff. i don’t get it

Step-by-step explanation:
Answer:
28.3 cm
Step-by-step explanation:
Let x represent the length of one side of the square. Then, by the Pythagorean Theorem,
x^2 + x^2 = (40 cm)^2, or
2x^2 = 1600 cm^2.
Thus, x^2 = 800 cm2, and x, the length of one side, is √800, or 28.3 cm to the nearest tenth of a cm.
